DETAILED DESCRIPTION

Cleaner and disinfectant kits are disclosed. The kit includes solid cleaning and/or disinfectant compositions, discussed in more detail below, and a bottle having a fill line at a volume sufficient to obtain a disinfectant solution of the disinfectant composition and water. The disinfectant composition is contained in a three-layer laminate material comprising an aluminum layer sandwiched between a polyethylene (PE) layer and a polyethylene terephthalate (PET) layer. The bottle can be glass, plastic or any other material capable of containing a liquid.

1 shows an exemplary disinfectant kit (1) according to the present invention. The kit (1) includes a bottle (20) and a spray head (40) for use with the bottle (20). The bottle (20) in the kit (1) is empty. The empty bottle (20) does not leak, which makes shipping easier. The empty bottle (20) is also lighter than a bottle with liquid, which makes shipping cheaper. The kit (1) also includes four pillow packs (16) containing the cleaning and disinfectant compositions. Further details of pillow packs (16) are discussed below. The kit (1) in 1 is a box (2), more precisely a carton. The box (2) protects the kit from damage during transport. The kit (1) may alternatively be any other type of container, such as a can, basket, can, box, crate, suitcase, or any other item that allows shipping the contents without departing from the teachings herein to deviate

A picture of an exemplary bottle (20) for use in the disclosed cleaning and disinfectant kits is in 3 provided. Preferably the material of the bottle is suitable for repeated refilling. Stability tests in Example 9 demonstrate that the solution prepared from the solid detergent and/or disinfectant composition does not react with polyethylene terephthalate (PET) bottles. Fill line (21) is at a volume sufficient to obtain a detergent and disinfectant solution having a concentration by weight of about 1.2% to about 2% citric acid and a concentration by weight of about 0.083% to about 0.15% sodium benzoate includes. In 3 the fill line (21) is indicated by a magic mark. Those of ordinary skill in the art will recognize that any form of marking may be used in the teachings herein, including labels, colored lines, etched or scored glass or plastic, bottle shape modification, and/or ridges or seams. The bottle (20) can be transparent or translucent to better see the fill line (21), but transparency or translucency is not mandatory. The bottle (20) can also have a spray head (40 - shown in 1 and 4 ) that delivers from about 0.75 mL to about 3 mL of liquid per spray, preferably from about 1 mL to about 2 mL per spray, and more preferably about 1.3 mL of liquid per spray. Those of ordinary skill in the art will recognize that effective germ kill is achieved if the surface is sprayed until wet, regardless of the volume of solution dispensed through the spray head.

4 Figure 12 is a flow chart demonstrating the method of using the disclosed kits. In 4 - Step 1 will add water to the fill line (21 in 3 and 5 ) admitted. Exemplary tablet(s) (10) will be placed in the bottle (20) in 4 - Step 2 given. The tablet(s) (10) will dissolve in water in about 15 minutes. Alternatively, the tablets (10) can be placed in the bottles (20) before the water is added. Those of ordinary skill in the art will recognize that this will increase the concentration of the ingredients due to the volume displacement caused by the tablet (10). In other words: the filling line (21) no longer represents the calculated full volume due to the volume displacement caused by the tablet(s) (10). The spray head (40) is 4 - Step 3 placed on the bottle (20). As shown in the examples, with the preferred formulation E6, the foam does not overflow, allowing the spray head (40) to be placed on the bottle before dissolution is complete. However, it is preferred to wait and confirm that dissolution is complete before attaching the spray head (40). The detergent and disinfectant solution can be used once the tablet (10) has completely dissolved. As shown in Example 9, the detergent and disinfectant solution is still stable after two weeks at 54°C and is expected to remain stable for up to two years at room temperature and humidity.

5 Figure 12 is a front perspective view of the bottle (20) used in the disinfectant kits disclosed above. The bottle (20) comprises a neck (22) connected to a body (23) by a concave shoulder (24). The transition between the shoulder (24) and the body (23) is inclined so that the transition is higher on one side of the bottle (20) than on the other. As a result, the base of the concave shoulder (24) is higher on one side of the bottle than on the other. this is in 5 shown as the lower concave shoulder approach (26) and the higher concave shoulder approach (25). The fill line (21) of the bottle (20) is at the base of the higher concave shoulder (25). The shoulder (24) occupies between about 5% to about 15% of the volume of the bottle and about 20% to about 30% of the vertical linear area of the bottle (20).

The horizontal diameter at the bottom (30) of the bottle (20) is longer than the horizontal diameter at any other diameter of the bottle (20). This configuration allows the bottle (20) to be fixed in the carton used for sale or delivery. In other words, the bottom (30) of the bottle (20) snaps into the carton used for sale, preventing consumers from taking bottles from shelf displays.

As in 5 shown, the shoulder is structured by horizontally oriented concentric rings (27) running parallel to the slope between the lower (26) and higher (25) shoulders; vertically oriented lines (28) parallel to the concave shoulders (24); and indentations (29) formed between the concentric rings (27) and vertically aligned lines (28). This structuring offers improved ergonomics, in particular a better grip of the bottle (20), whether wet or dry. When the bottle (20) is made from 100% recycled (PCR) polyethylene terephthalate (PET), this structuring also shows different shapes at different angles. With the disinfectant compositions disclosed herein, the 100% PCR PET bottle (20) can be reused between 1 and 100 times, preferably between 10 and 30 times before it starts to degrade and needs to be recycled. Alternatively, the bottle (20) may be formed from a compostable and recyclable waterproof paper laminate material such as those disclosed in PCT Publication Nos. WO2022/027047 by Procter & Gamble, WO2022/026716 by Frito-Lay North America Inc. or WO2020/178798 by Greentech Global PTE Ltd. are revealed.

The bottle (20) further includes a neck (22) which holds the spray head (40 in 1 and 4 ) records. The spray head may be snap-on, screw-on, hybrid snap-on-screw or press-fit type. The spray head can have a child safety functionality. The spray head delivers about 0.75 ml to about 3 ml of liquid per spray, preferably about 1 ml to about 2 ml per spray, and more preferably about 1.3 ml of liquid per spray.

Also disclosed are detergent packs containing any of the disinfectant compositions disclosed above. The detergent packs comprise a three-layer laminate material (15). The three-layer laminate material (15) comprises an aluminum layer sandwiched between a polyethylene (PE) layer and a polyethylene terephthalate (PET) layer. The PE layer contacts the disclosed disinfectant compositions. The three-layer laminate material (15) comprises an aluminum layer having a thickness ranging from about 6 microns to about 10 microns, preferably ranging from about 7 microns to about 9 microns; a PE layer having a thickness in the range of about 28 microns to about 32 microns, preferably in the range of about 29 microns to about 31 microns; and a PET layer having a thickness ranging from about 10 microns to about 14 microns, preferably ranging from about 11 microns to about 13 microns.

The detergent pack or packaging container is referred to as a pillow pack (16). The pillow pack (16) is formed by three seams in overlapping sections of the three layer laminate material (15), a top seam (17) spanning a width at one end, a bottom seam (18) spanning the width at the opposite end , and a side seam (19) spanning a length between the end seams. 6a Figure 12 is a plan view of the tubular pillow bag (16) formed from the three layer laminate material (15) and containing the disinfectant compositions disclosed herein. 6b Figure 12 is a side view of the tubular pillow bag (16). It is known that the pillow packs compared to alternative sealing structures such. B. the laminate envelopes with 3 or 4 sealed sides, have sealing defects. Sealing failures are obviously problematic for the hygroscopic formulations containing citric acid. As shown in the following examples, the disclosed disinfectant compositions were stable in the pillow packs made from the three-layer laminate material, but were not stable in pillow packs made from tubular bags made from films of metallized , bi-oriented polypropylene (OPP).

Powdered or tableted disinfectant composition may be contained within the tubular pillow bag (16). The tubular pillow bag may contain between 1 and 12 disinfectant tablets, preferably between 2 and 9 disinfectant tablets, more preferably between 3 and 6 disinfectant tablets and most preferably 3 or 4 disinfectant tablets. The tubular pillow pack measures from about 110mm to about 130mm in length and from about 20mm to about 30mm in width and when containing three tablets weighs between about 5g and about 15g, preferably between about 7. 5g and about 12.5g. When the tubular pillow pack contains the acidic disinfectant tablets disclosed above, each of the three tablets preferably weighs between about 7.5 and about 10 grams. When the tubular pillow pack contains the basic disinfectant tablets disclosed above, each of the three tablets preferably weighs between about 10 and about 12 grams.

Solid cleaning and/or disinfectant compositions for use in the disclosed disinfectant kits are also disclosed. The acidic solid cleaner and/or disinfectant compositions include a synergistic combination of citric acid and sodium benzoate. The basic solid cleaning and/or disinfecting compositions contain a combination of citric acid, benzalkonium chloride and nonionic surfactants. When the solid cleaning and/or disinfecting agent compositions are dissolved in water, the resulting cleaning and/or disinfecting agent solutions exhibit superior germ killing. The acidic formulation also provides superior CPSA soap scum and lime scale removal.

Citric acid is a well-known disinfectant. See e.g. B., Dvorak, Disinfection 101, Center for Food Security and Public Health, May 2008. Lemon juice is a commonly used ingredient in eco-friendly cleaning. Lemon juice contains around 5-8% citric acid, along with other potentially disinfecting ingredients like malic acid, ascorbic acid, and essential oils. However, it also leaves a sticky residue.

Citric acid is also hygroscopic, making it difficult to use in large quantities in tablets. See Example 2 below. As a result, coated or encapsulated citric acid products have been developed. See e.g. B. U.S. Patent No. 2,956,926 by griffin. Optimization of the type and amount of coating is required to achieve the desired tablet properties.

Applicants have discovered that citric acid encapsulated by a binder provides the reaction and dissolution rates required for the present formulation. Polysaccharide binders such as maltodextrin are preferred. Maltodextrin has a melting point of 240°C. Applicants believe that polysaccharides or other binders with similar melting points can work effectively in the present invention. Citric acid DC sold by JBL, which contains 96% by weight citric acid in a maltodextrin binder, works particularly well. The particle size of the citric acid DC powder is 5% maximum > 0.63 mm and 5% maximum < 0.100 mm.

In tablet embodiments, the binder encapsulation may provide sufficient binding activity to form a tablet such that an additional binder is not required in the solid formulation. Alternatively, the solid formulation may contain an additional binder such as that alcohol ethoxylates sold by BASF under the trade name Lutensol™ AT 25 or the polyethylene glycols sold by BASF under the trade names Pluriol™ E4000 or Pluriol™ E6000. Any additional binder should be selected so that the rate of dissolution is not affected.

Alternatively, a co-crystal of citric acid can be used. Co-crystals are solid crystalline structures containing two or more solid components held together in a defined stoichiometric ratio by non-covalent forces. Because water is liquid at room temperature, hydrates are not considered co-crystals. Likewise, co-crystals do not involve two or more materials crystallizing simultaneously, but rather in individual and separate crystal lattices (simultaneous crystallization).

A citric acid-nicotinamide co-crystal can be prepared by mixing 250 mg of a 1:2 molar ratio mixture of citric acid and nicotinamide in a stainless steel beaker with 100 µl of ethanol using 2 7 mm diameter stainless steel grinding balls. The mixture is ground in a Retsch MM200 ball mill at a frequency of 30 Hz for about 30 minutes. See e.g. B. Pagire et al., Improving the Stability of Effervescent Products by Co-Crystal Formulation: A Novel Application of Crystal Engineered Citric Acid, Cryst. Growth Des., 2020, 20, 7, 4839-4844. Alternatively, the co-crystal can be formed from citric acid combined with ascorbic acid, malic acid, tartaric acid, isonicotinamide, histidine, urea, saccharin, glycine, tyrosine, vanillin and/or valine. See e.g. B. PCT Publication No. WO2016/001681 the University of Bradford.

In a further alternative, the solid disinfectant formulation may further comprise a water-soluble polymer or biofilm sealant with residual activity, such as a polyethyloxazoline. Suitable polyethyloxazolines include 2-ethyl-2-oxazoline sold by Polymer Chemistry Innovations, Inc. under the trade name Aquazol™ 500. The polymer concentration can range from about 0.05% to about 5% by weight. Preferably, the concentration is chosen to minimize the effect on dissolution of the disinfectant formulation in solution while still producing a thin coating on the surface to which it is applied.

Applicants have found that solid formulations containing from about 50% to about 75%, preferably from about 51% to about 60%, and more preferably from about 52.3% to about 57.8% by weight citric acid encapsulated by a binder, provide sufficient reactants for bubbling and germ killing in the solution. The resulting solution contains a weight concentration of from about 1.2% to about 2% citric acid, preferably from about 1.3% to about 1.6%. One of ordinary skill in the art would know how to calculate the amount of solid composition and volume of water needed to produce the desired concentration of citric acid in solution with or without effervescent.

Alternatively, the disclosed disinfectant formulations comprise between about 63% and about 66% by weight citric acid encapsulated by a binder. The resulting solution contains a weight concentration of 2% to 2.2% citric acid.

Applicants have also surprisingly discovered that improved germ kill is obtained by a combination of citric acid and sodium benzoate. As discussed above, lemon juice contains 5-8% citric acid, alongside other potentially disinfecting ingredients such as malic acid, ascorbic acid, and essential oils. Prior to this project, R&D tests had shown that aqueous solutions containing 2.5% by weight citric acid had not provided consistent or satisfactory germ kill results. Surprisingly, the inventors have discovered that aqueous solutions containing from about 1.2% to about 2% by weight citric acid and from about 0.05% to about 0.15% by weight sodium benzoate provide reproducible, consistent sanitization results. without the need for additional biocides such as peroxides, quaternary ammonium compounds, phenols, biguanides or parachlorometaxylenol (PCMX).

Applicants have found that tablets containing from about 1% to about 5.5%, preferably from about 2% to about 5%, and more preferably from about 3.6% to about 4.4% by weight sodium benzoate provide the concentration , which is required for increased germ killing in the solution. Again, one of ordinary skill in the art would know how to calculate the amount of solid composition and volume of water needed to produce the desired concentration of sodium benzoate in solution.

Concerns have been raised that the combination of citric acid and sodium benzoate produces benzene at low pH (below 3.8 according to Johnson above). Sodium benzoate has a pKa of 4.2, which means there is slightly more benzoic acid in a solution with a pH of 3.8. The anionic detergent surfactants help increase the pKa of sodium benzoate. See e.g. B. Formulations with Kalaguard™ SB from Emerald Performance Materials. This reduces the amount of benzoic acid in solution and the potential for benzene contamination.

Also disclosed are basic solid detergent and/or disinfectant compositions containing between about 10% and 16% by weight citric acid encapsulated by a binder. The citric acid provides sufficient reactant for the bubbling. In this embodiment, all of the citric acid is consumed in the bubbling reaction. The resulting solution contains a weight concentration of 0% to less than 0.001% citric acid.

Both the acidic and the basic solid detergent and/or disinfectant compositions may also contain an effervescent agent such as an alkali carbonate and/or alkali bicarbonate. Exemplary alkali carbonates include sodium carbonate, potassium carbonate, the corresponding hydrate salts thereof, and mixtures thereof. Exemplary alkali bicarbonates include sodium bicarbonate, potassium bicarbonate, the corresponding hydrate salts thereof, and mixtures thereof. The effervescent helps accelerate the dissolution of the solid composition in tap water. As shown in the reaction below, the alkali carbonates react with citric acid to generate bubbles of carbon dioxide. _{2H3C6H5O7 + 3Na2CO3 → 2Na3C6H5O7 + 3CO2 + 3H2O _ _ _}

The acidic cleaning and/or disinfecting compositions contain an excess of citric acid, resulting in acidic solutions in water. The basic detergent and/or disinfectant compositions contain an excess of carbonate, resulting in basic solutions in water.

In the acidic formulations, the concentration of citric acid must be increased so that an effective concentration of citric acid remains in solution. The solid compositions are formulated such that all of the alkali carbonate and/or alkali bicarbonate is consumed during the effervescence reaction. The solution produced from the reaction of the solid composition with water contains little to no alkali carbonate and/or alkali bicarbonate, as evidenced by the low pH of the resulting solution. The concentration of alkali carbonate or alkali bicarbonate is chosen to produce sufficient carbon dioxide to mix the ingredients with water without foam overflowing from the bottle. Applicants have found that in the present formulations, from about 6.5% to about 8.3% by weight sodium carbonate grade 100 provides suitable foaming performance. Alternatively, from about 5% to about 7% by weight sodium bicarbonate can be used. Those of ordinary skill in the art will recognize that different concentrations may be required for alternative carbonates and bicarbonates without departing from the teachings herein.

In the basic formulations, the concentration of carbonates is increased such that an effective amount of carbonate remains in solution. The solid compositions are formulated so that all of the citric acid is consumed during the effervescent reaction. The solution produced from the reaction of the solid composition with water contains little to no citric acid, as evidenced by the high pH of the resulting solution. The concentration of citric acid is chosen to produce enough carbon dioxide to mix the ingredients with water without foam spilling out of the bottle. Applicants have found that in the present formulations from about 10% to about 16% by weight citric acid provides suitable foaming performance.

As shown in Example 13 below, the base formulations preferably contain a carbonate. The carbonate offers stability advantages over the bicarbonate by allowing more moisture to be absorbed in the final product before the autocatalytic reaction begins. The basic formulations contain from about 45% to about 60% by weight carbonate, preferably from about 50% to about 55%. The carbonate can be potassium carbonate, sodium carbonate, potassium carbonate hydrate, sodium carbonate hydrate, or combinations thereof. The carbonate hydrates show better surfactant absorption than the non-hydrate forms of carbonate, which improves tablet formation.

Applicants have discovered that tablet formation improves when the raw materials have different particle sizes. The applicant considers that raw materials with different Particle sizes provide a better tablet matrix. Preferably, the sodium carbonate has a particle size of 85% a minimum of 150 microns or greater and a particle size of 50% a maximum of 420 microns or less. The potassium carbonate solid is 63% particle size <45 microns, 22% particle size in the range 45 microns to 90 microns, 13% particle size in the range 90 microns to 150 microns, and 2% particle size in the range from 150 microns to 250 microns.

The basic solid detergent and/or disinfectant composition includes benzalkonium chloride. The concentration of benzalkonium chloride in the basic solid detergent and/or disinfectant composition ranges from about 4% to about 5.2% by weight. Preferably, the basic solid detergent and/or disinfectant composition comprises a mixture of C12-14 alkyldimethylethylbenzyl quaternary ammonium chloride and C12-18 alkyldimethylbenzyl quaternary ammonium chloride in an inert matrix. A suitable source of the mixture of C12-14 alkyldimethylethylbenzyl quaternary ammonium chloride and C12-18 alkyldimethylbenzyl quaternary ammonium chloride in an inert matrix is BTC 2125M P40 in urea with an average particle size of 117 µm from Stepan.

The acidic solid detergent and/or disinfectant composition may further contain a detergent surfactant such as an anionic surfactant. Exemplary anionic surfactants include sodium lauryl sulfate, sodium laureth sulfate, sodium lauryl methyl isethionate, and combinations thereof. The detergent surfactants improve the cleaning properties of the product. Solid detergency surfactants are preferred for ease of tablet formulation. Preferably, the cleaning and/or disinfecting compositions comprise from about 14.7% to about 18% by weight sodium lauryl sulfate. The sodium lauryl sulfate has a bulk density ranging from about 0.5 g/mL to about 0.7 g/mL.

The basic solid detergent and/or disinfectant composition may further contain a detergent surfactant such as a nonionic surfactant. The nonionic surfactant also serves as a binder due to the small amount of citric acid present in the basic formulations. The composition comprises between about 7% and about 9% nonionic surfactant by weight. Exemplary nonionic surfactants include liquid alkoxylated alcohols. Applicants have found better cleaning with shorter chain alkoxylated alcohols. Undecyl alcohol ethoxylate is particularly useful for cleaning polymerized grease. The shorter chain alkoxylated alcohols are also more soluble than their longer chain analogs. The nonionic surfactant can have from 3 to 10 degrees of ethoxylation, preferably between 4 and 9 degrees of ethoxylation, and more preferably between about 5 to 8 degrees of ethoxylation. Particularly preferred nonionic surfactants include undecyl alcohol ethoxylate having from 3 to 10 moles of ethoxylation, preferably between 4 and 9 ethoxylation, and more preferably having between about 5 to 8 ethoxylation. These surfactants are sold by Stepan under the Makon™ UD product line, including but not limited to Makon UD-5, Makon UD-6, and Makon UD-8, or mixtures thereof. A mixture of undecyl alcohol ethoxylate with 5 moles of ethoxylation and undecyl alcohol ethoxylate with 8 moles of ethoxylation showed superior cleaning results compared to formulations containing a single alcohol ethoxylate.

Both the acidic and the basic solid cleaning and/or disinfecting composition can also contain a chelating agent to keep the final solution clear. Suitable chelating agents include methylglycine diacetic acid trisodium salt ("MGDA", also known as trisodium N-iminodiacetate or trisodium alpha-DL-alanine diacetate), ethylenediaminetetraacetic acid (EDTA), tetrasodium glutamate diacetate (GLDA), tetrakishydroxymethylphosphonium sulfate (THPS), diethylenetriaminepentaacetic acid (DTPA), or combinations from that. In the acidic formulations, the chelating agent should be effective at a low pH ranging from about 2 to about 5, preferably from about 3 to about 4. As shown in the examples below, MGDA has performed well in both acidic and basic formulations.

The solid cleaning and/or disinfecting compositions may include other adjuvants commonly used in household cleaning products, such as fragrance, colorant, fillers, binders, or combinations thereof. Because of the solid formulation, the fragrance is preferably in powder form or spray-dried. The powdered or spray-dried fragrance preferably contains from about 10% to about 50% by weight of the fragrance oil on a suitable substrate. Exemplary substrates include starches, silica formulations, silica and salt such as sodium chloride or potassium iodide, or combinations thereof.

The combined liquid content of all ingredients in the acidic formulation must not exceed 10% by weight of the final solid formulation, and preferably ranges from about 0.1% to about 7.5% by weight.

The combined liquid content of all ingredients in the base formulation should not exceed 15% by weight of the final solid formulation and preferably should range from about 0.1% to about 11% by weight.

The solid detergent and/or disinfectant composition may be in powder or tablet form. The powder or tablet may be encapsulated in a water soluble or removable film. Suitable water soluble films include polymeric films or water soluble paper. Alternatively, the powder may be provided in single use or multiple use containers such as a sachet or bucket. Multi-use containers may be accompanied by an appropriately sized spatula.

The weight of the cleaning and/or disinfecting tablets can range from about 0.5 g to about 500 g, preferably from about 1 g to about 30 g, more preferably from about 5 g to about 10 g. The solid detergent and/or disinfectant composition is sized to suit its intended purpose. Smaller sized tablets may be provided for single use and will range in weight from about 0.5g to about 1g. Larger tablets ranging from about 400g to about 500g can be provided for commercial use such as hotel or other large scale cleaning operations. Applicants have found that three (3) 8.3g tablets are of a suitable size for use in standard 750ml cleaning bottles.

The tablets have an overall hardness that can be measured by acceptable industry standards, such as USP Test Method 1217, or using appropriate tablet hardness testers. The breaking load can be determined in kiloponds (kp). A kilopond is a metric unit of force, where 1 kgf equals 9.807 newtons. The hardness of the tablets may range from about 0.2 to about 8 kp, preferably from about 0.7 to about 5.8 kp, more preferably from about 1.5 to 5.5 kp and most preferably from about 2 to about 5.2 kp.

The tablets are also analyzed for crush strength using tablet friability tests according to industry standards such as USP Test Method 1216 or other acceptable standards. Using an ERWEKA TAR 220 friability tester at 25 rpm, the tablet friability weight loss reading is less than 5 percent weight loss, preferably less than 4 percent, more preferably less than 3 percent, and most preferably less than 2 percent.

Alternatively, the basic solid detergent and disinfectant composition comprises, consists essentially of or consists of:

1. a. 4 to 5.2% by weight benzalkonium chloride;
2. b. a weight fraction of 14 to 16% citric acid encapsulated by maltodextrin with an average particle size < 0.63 mm;

To mix the disclosed acidic cleaning and/or disinfecting compositions, the ingredients are blended in a powder blender, such as a ribbon blender, until uniform. Due to the effervescent nature of the formulation, complete ingredient uniformity is not required. For tablets, the desired tablet weight is measured from the uniform formulation and placed on the die of a tablet press. The cleaning and/or disinfection tablet is produced by compressing it with a tablet press. In R&D tests, the pressure was set at 80N. During scale-up testing, Applicant discovered that the use of granulated sodium lauryl sulfate produces tablets that are less friable than those made with powdered sodium lauryl sulfate. Those of ordinary skill in the art will recognize that the specific ingredients and tablet size will determine the pressure required to manufacture the cleaning and sanitizing tablet. Some example tablets are in 2 pictured.

Mixing instructions for the basic cleaning and/or disinfectant composition are given in Example 11 below.

Neither the acidic nor the basic cleaning and/or disinfecting formulations contain added water. The explicit addition of water to the formulations can induce an early reaction between the fizzy components. Any water molecules contained in the raw materials do not integrate with other ingredients in the solid formulation, forming a hydrate solid or crystal lattice.

For shipping and sales purposes, the tablets may be wrapped in a metallized bi-oriented polypropylene (OPP) horizontal flow wrap film laminated with a polypropylene sealing film. Alternatively, the tablets may be wrapped in a tubular pouch made from a three-layer laminate material comprising an aluminum layer sandwiched between a polyethylene (PE) layer and a polyethylene terephthalate (PET) layer. As shown in the following examples, the tubular bag made of three layer laminate material is preferred.

The solid mixtures are dissolved in water to produce the disclosed cleaning and/or disinfectant solutions. Depending on the ingredients of the solid composition, the dissolution time can range from about 1 minute to about 60 minutes. The dissolution time is shorter when the formulation contains an effervescent, ranging from about 10 minutes to about 20 minutes. The rate of the bubbling reaction can be increased by increasing the temperature of the water. As disclosed in the following examples, the level of effervescent was optimized to prevent excessive foaming.

The acidic solid mixtures are dissolved in water to produce the disclosed cleaning and/or disinfectant solutions. The amount of water should be sufficient to prepare a cleaning and/or disinfectant solution comprising a concentration by weight of about 1.2% to about 2% citric acid and a concentration by weight of about 0.083% to about 0.15% sodium benzoate. In the following examples, 25 g of acidic solid mixture was placed in 750 ml of water. When an effervescent agent is included, the resulting solution foams little. Those of ordinary skill in the art will recognize that the amount of solid composition and volume of water can be changed without departing from the teachings herein. For example, two tablets of 12.5 g each in 750 ml of water can be used. Alternatively, one (1) 10g tablet may be added to 300ml of water.

The disclosed cleaning and/or disinfectant solutions reduce the microbial load on a variety of hard surfaces, including but not limited to countertops, floors, walls, sinks, toilets, toilet bowls, bathtubs, and the like. Exemplary hard surfaces include brick, cement, ceramic, crystal, diamond, fiberglass, glass, latex, linoleum, marble, metal, metal alloy, pebble, porcelain, polymeric, quarry tile, natural stone, wood, and mixtures thereof surfaces.

Alternatively, the disclosed disinfectant kits may comprise a carrier substrate, e.g. a product or article of a swipe type. Unlike quaternary germicides, citric acid is not known to bind to nonwoven substrates, leaving it chemically available to produce a germicidal effect. A suitable amount of solid composition can be provided with a set of dry wipes and wipes dispensing containers with a fill line. As above, the water is added to the fill line and the solid composition is added to the water. Once dissolved, the wipes can be added to the resulting solution. Alternatively, the solution and wipes can be combined in a wipes dispenser pack.

Fiber materials made from natural and/or synthetic fibers can advantageously be used. The nonwoven fabrics can be a combination of viscose, lyocell, wood pulp fibers, and synthetic fibers in textile lengths formed by dry-forming or wet-laid processes. Synthetic fibers such as nylon, orion, polyester, and polypropylene, and blends thereof can be used. Such may be woven or non-woven fabrics or pads. Such may be spunlace, spunbond, wet-laid, resin-bonded, hydroentangled, thermally-bonded, melt-blown, needle-punched, or any combination of the foregoing. The substrate of the wipe can also be a film-forming material such as a water-soluble polymer. Such film substrates can be sandwiched between layers of fabric substrates and heat sealed to form a useful substrate. The films themselves can be extruded using standard equipment to degas the formulation. A casting process can be used to form and dry films, or a liquid formulation can be saturated into a vehicle and then dried in a variety of known methods.

Suitable pads or towels may contain little or no cellulosic materials. Alternatively, pads or towels can be used that are predominantly (e.g. more than 50%) based on cellulose fibers. Especially preferred are pads or wipes based on natural fiber sources such as cotton or wood pulp because of their effectiveness, ready availability and low cost. More preferably, the pads or towels are at least 60%, and in order of increasing preference at least 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, and 100% cellulosic, closed cell, or open-cell foams are also suitable as pads or cloths. Such foams include polyurethane foams and regenerated cellulose foams, which may also be referred to as sponges.

Exemplary commercially available wipes include 45 or 70 grams per square meter (GSM) 100% regenerated cellulose sold by Spuntech Industries Inc.; 100% viscose with 35 or 40 GSM distributed by Sandler AG; 50% Polypropylene and 50% Woodpulp at 40 GSM distributed by Berry Global Inc.; 65% wood pulp and 35% polypropylene at 35 GSM sold by Suominen Corp; a weight fraction of 50% viscose and 50% polyethylene terephthalate at 45 GSM sold by Spuntech Industries Inc.; a weight fraction of 51.1% wood pulp, 26.7% polypropylene and 22.2% polyethylene terephthalate at 45 GSM sold by Suominen Corp; 41.73% wood pulp, 40.27% polypropylene and 18% polyethylene terephthalate at 55 GSM distributed by Suominen Corp & Atex Inc.; and 100% Polypropylene at 45 and 55 GSM distributed by PF Nonwovens Czech s.r.o.

Any of the foregoing wiping-type products or articles may include a laminate layer, such as a liquid impervious layer, which may be useful to prevent wicking of the treatment composition onto a portion or surface of the pad, cloth or sponge limit.

Pre-soaked wipes can be provided in any suitable loading ratio of the disclosed detergent and disinfectant solution: non-impregnated pad or wipe, but preferably such loading ratio is in the range of about 0.1-5:1 parts by weight, preferably 0.5-5:1 parts by weight .

The cleaner and disinfectant solution provides a 5 log ₁₀ reduction in Staphylococcus aureus on a hard surface in about 10 minutes, preferably in about 5 minutes, and more preferably in about 2 minutes. Applicants believe that similar results are obtained with typical infectious microorganisms, including Salmonella typhi and non-enveloped viruses.

The surface can be wiped off after 2, 5 or 10 minutes to remove any residual liquid. Applicants believe the formulation will not leave a sticky residue. Banding confirmation tests are planned to verify these unquantified R&D results.

In addition to killing germs, the disclosed cleaning and disinfectant solution provides superior cleaning results, as demonstrated in the following examples. In particular, the disclosed solutions provide removal of loose grease, CSPA soap scum and (-)limescale equal to or superior to commercial formulations.

Those of ordinary skill in the art will recognize that concentrated formulations that provide both germkill and cleaning are typically expensive. Concentrated formulations typically require more raw materials to achieve adequate sanitization and cleaning. The disclosed solid compositions successfully balance raw material cost requirements while maintaining product efficacy.

The following examples illustrate exemplary embodiments of the invention. It should be understood that these examples are illustrative only and that other embodiments may be made in accordance with the teachings of the present invention.

Example 1: pH, dissolution time and foam height of acidic formulations

The ingredients in Table 1 were mixed in a plastic bag. The formulation was weighed and placed in tablet form. The tablet was hand compressed using a tablet press. This was repeated twice for each formulation. 750 mL (25.4 ounces) of tap water was heated to 50°C in 800 mL bottles. Three (3) tablets of each formulation E1-E6, weighing an average of 24-26 g, were placed in tap water in separate bottles labeled to represent the formulation E1-E6 contained therein. No mixing was required due to the effervescent nature of the tablets. The dissolution time was measured. Any foam overflow was also noted. 3 Figure 12 is an example image of a positive foam overflow result. The pH was measured on tablets dissolved in 750 mL (25.4 ounces) of deionized water at room temperature. The formulations and test results are given in Table 1: Table 1: shortcut E1 E2 E3 E4 E5 E6 E7 SLS (96% active level) 15.2 (14.6) 15.62 (15.0) 12.03 (11.5) 16.91 (16.2) 14.78 (14.2) 16.32 (15.7) 13.2 (12.7) CA (96% active level) 51.29 (49.2) 52.70 (50.6) 54.94 (52.7) 57.08 (54.8) 55.10 (52.9) 55.08 (52.9) 64.31 (61.7) Scarb 0 11.54 12.03 4:17 9.05 7.54 0 Sbicarb 13.89 0 0 0 0 0 6.05 MGDA (76% active level) 7.4 (5.6) 7.6 (5.8) 7.92 (6.0) 8.23 (6.3) 7.95 (6.0) 7.95 (6.0) 6.9 (5.2) SBenz 3.75 3.86 4.02 4:18 4.03 4.03 3.83 f 8.44 8.66 9.02 9.40 9.05 9.05 5 D 0.03 0.03 0.03 0.03 0.03 0.03 0.0263 EO6 0 0 0 0 0 0 0.69 pH NO NO NO 2.93 NO 3.25 2.83 resolution time 15 minutes 15 minutes 15 minutes Has not fully resolved 14 minutes 15 minutes 13 minutes Foam overflow?

As can be seen from Table 1, higher concentrations of sodium bicarbonate or sodium carbonate resulted in foam overflowing from the top of the bottle. Foam overflow creates a negative consumer experience because the cap or spray head cannot be immediately placed on the container without causing mess. In addition, water and detergent can be lost, which negatively affects the effectiveness of the cleaner. In contrast, too low a concentration of sodium carbonate resulted in longer tablet dissolution times, as shown for Formulation E4. This effect is also undesirable since the consumer will question whether the solution has reached its full cleaning potential. Consumers prefer clear or transparent cleaning solutions, not cloudy solutions, Formulation E6 gave the best results.

Example 2: citric acid

R&D formulations similar to formula E1 in Example 1 were tested using anhydrous citric acid or citric acid coated with sodium citrate sold as Citrocoat™ N by Jungbunzlauer (JBL). Anhydrous citric acid was too hygroscopic for use in a tablet formulation. During the stability test, the tablets increased in size, showing water absorption. Citric acid coated with sodium citrate did not show suitable tabletting properties and broke up into a loose powder after ejection from tablet form. Consequently, applicants believe that sodium citrate coatings do not provide adequate binding capabilities, at least in part due to higher melting points (300°C) than maltodextrin (260°C).

Example 3: Disinfection analysis

Applicants have surprisingly discovered that the germicidal effectiveness of citric acid is significantly enhanced by the addition of sodium benzoate. It is known that sodium benzoate or citric acid solutions provide limited to no germ kill at pH levels in the 5-8 range and that germ kill increases as the pH decreases. Adamczak et al. disclosed that a solution of 1 mg/ml citric acid in a 20% aqueous solution of dimethyl sulfoxide was inactive against Staphylococcus aureus. Antibacterial Activity of Some Flavonoids and Organic Acids Widely Distributed in Plants, J. Clin. Med., 2020, 9, 109.

When diluted, formula E6 gives a weight concentration of 1.3% active citric acid (1.3 g/ml ö 192.2 g/mol x 1000 ml/l = 6.8 M) and a weight concentration of 0.13% sodium benzoate at a pH of 3.25. After a contact time of 10 minutes, the Association of Official Analytical Chemists International (AOAC) Germicidal Spray Products as Disinfectants (GSP) test was 961.02 under dirty conditions the total number of positive test results/total number of tested Formula E6 samples 0/60 against Staphylococcus aureus (ATCC 6538). As is well known in the art, S. aureus is one of the more difficult organisms to kill by organic acids and therefore provides an indication that this formulation will also be successful against other organisms. See e.g. B. above Adamczak et al. A pre-dilution containing 1.25% w/w active citric acid and 0.26% w/w sodium benzoate produced 0/60 against both S. aureus and S. enterica after 10 minutes contact time. Applicant anticipates that formulations having a weight concentration of 1.3% citric acid without sodium benzoate will have difficulty successfully killing S. aureus.

One of ordinary skill in the art will recognize that removing the citric acid or sodium benzoate from these test formulations increases the total weight percentage of the remaining ingredients. Consequently, the same weight of material was used in all three formulations, with the size of the sample added to tap water being changed to reflect the material change. This procedure ensures that the same amount of material is compared and only the amount of active ingredients changes.

As can be seen from Table 2, although all the citric acid is consumed during the bubbling, the pH of C2 remains below 7.5. Applicants believe that some sodium citrate may remain in the formulation as indicated by the neutral pH. In contrast, sodium benzoate without citric acid in formula C3 does not kill germs at the same concentration. Likewise, Formula C1 without sodium benzoate provides no germ kill. These results show the synergistic germicidal effect achieved by the combination of citric acid and sodium benzoate.

These results lead applicant to believe that these formulations containing the combination of citric acid and sodium benzoate can also be used successfully to kill enveloped viruses such as Herpesviridae and Pleolipoviridae. Additional microtest results are given in Example 10 below.

The procedure used is based on ASTM D4488 A2 - Standard Guide for Testing Cleaning Performance of Products Intend for Use on Resilient Flooring and Washable Walls

Fine porosity cellulose sponges are cut to 4.445 cm (1.75 inches) by 9.2075 cm (3.625 inches) by 3.81 cm (1.5 inches). The sponges are rinsed and spun three times in a Maytag washing machine using only warm water to ensure that the sponges are free of contaminants/preservatives and to provide an even moisture level for all sponges. The sponges are then placed in a tightly sealed bag to retain moisture until use.

A 0.3175 cm (0.125 inch) by 11.43 cm (4.5 inch) by 11.43 cm (4.5 inch) masonite fiberboard is double coated with a latex paint and allowed to cure overnight. The reflectance of the white panel before soiling is measured and recorded as R3.

The dirt for cleaning is freshly prepared daily in a 600 ml Pyrex ^® beaker in a 55 °C steam bath. By weight, 33% vegetable fat, 33% vegetable oil, 33% lard, and 1% lampblack are mixed in the heated beaker.

A cheesecloth is folded in half several times to make a 6.35 cm (2.5 inch) by 5.08 cm (2 inch) piece. A retaining clip is placed along the 6.35 cm edge of the folded cheesecloth.

Using the clip as a handle, the muslin cloth is soaked in the heated dirt and the dirt is applied to the white-painted masonite wood fiber board with six strokes. The temperature of the soil must be maintained and the soil must be agitated throughout the application process. The soiled substrate is allowed to dry overnight at room temperature. The degree of reflection of the soiled plate is measured either with a three-angle gloss meter, e.g. B. from BYK Gardner, or by means of digital imaging, z. B. a digital monochrome camera and suitable software such as Image Pro Plus measured and recorded as R2.

Each panel is divided into two equal halves with tape. The panels are numbered and the treatment given to each side is indicated.

The soiled panel is placed on the platform of the Gardner Abrasion Tester (no tray) such that the soiled portion of the panel is perpendicular to the direction of sponge movement such that the sponge scrubs an area in the center of one half of the panel.

The sponge is placed in the holder and 15 grams of test product is poured onto the sponge. One half of the panel is scrubbed umpteen times and immediately rinsed with cold, running tap water. The position of the plate is reversed to repeat the process on the other half of the plate with a new sponge and product sample. The reflectance of the cleaned panel is measured and recorded as R1.

Percent cleaning effectiveness is measured as [(R1-R2)/R3-R2)]x100. The test is repeated three times for each formulation. The results are given in Table 4. Table 4: E1 C4 C5 C6 C7 water loose fat 51:19 52.39 43.38 37.97 21.81 9.42

The results show the percentage of soil removed from the panel. Higher percentages indicate better cleaning. C4 is considered one of the best loose grease cleaners on the market. It can be seen that formulation E1 provides comparable cleaning results. Formula E1 is also superior to Formula C5, which has similar ingredients.

Although Formula E1 differs from Formula E6 in foam generation, the cleaning structure is similar and similar cleaning results against loose grease are expected from Formula E6. More specifically, all of the sodium carbonate or sodium bicarbonate is consumed during the production of the carbon dioxide bubbles and therefore does not contribute to the purification effect.

Example 5: Removal of CSPA soap scum by acidic formulations

A comparison of the soap scum removal effectiveness of formula E1, water and three different cleaning formulations from Table 3 was made.

Soap removal effectiveness was evaluated based on CSPA DCC 16 Part 2.

A 10.76 cm x 10.76 cm black bathroom tile is cleaned using ethanol and allowed to dry overnight in a 105°C oven. The reflectance of the surface This tile is measured with either a three-angle gloss meter, e.g. B. from BYK Gardner, or by means of digital imaging, z. B. a digital monochrome camera and suitable software such as Image Pro Plus measured and recorded as R3.

A soil source is prepared in a 600 ml ^Pyrex® beaker in a 55°C steam bath. The weight fractions are 3.90% stearic acid bar, 0.35% shampoo (with moderate alkyl ethoxylate without conditioner), 0.06% Black Clay (Black Charm Clay), 0.15% artificial sebum and 95.54% hard water. The final soil is mixed on the day of application. The final formulation consists of parts by weight of 4.50% soil source, 9.00% hard water, 0.77% hydrochloric acid 0.1N and 85.73% acetone. This is homogenized for 30 minutes.

The tiles are cooled to room temperature and weighed.

The tiles are placed on an inclined board. The soil is applied in one continuous motion with a spray gun until the amount of soil on the tile is between 0.10g and 0.15g. The tiles are air dried for 15-30 minutes and weighed again to verify that the weight remains within the range given above.

The tiles are then heated in an oven at 205°C for either 25-30 minutes or until the tiles have a matt finish. After cooling, the reflectance of the tile is measured and recorded as R2.

Each tile is divided into two equal halves with tape. The tiles are numbered and the treatment given to each side is indicated.

The soiled tile is placed on the platform of the Gardner Abrasion Tester (no tray) such that the soiled portion of the tile is perpendicular to the direction of sponge movement such that the sponge scrubs an area in the center of one half of the tile.

The sponge is placed in the holder and 2.0 grams of test product is poured onto the tile surface with a disposable pipette. A contact time of 30 seconds is scheduled for cleaning. One half of the tile is scrubbed 10 times and immediately rinsed with cold running tap water. The tile is dried with compressed air. The position of the tile is reversed to repeat the process on the other half of the tile with a new sponge and product sample. The reflectance of the cleaned tile is measured and recorded as R1.

The percent soap scum removal is measured as [(R1-R2)/R3-R2)]x100. The test is repeated three times for each formulation. The average of the four results is given in Table 5. Table 5: E1 C4 C5 C7 water Removal of soap scum 29.5 9.82 16.18 10.5 13.0

It can be seen that formula E1 provides better soap scum removal than any of the comparative examples.

Although Formula E1 differs from Formula E6 in foam generation, the cleaning structure is similar and similar results are expected from Formula E6 for soap scum removal. More specifically, all of the sodium carbonate or sodium bicarbonate is consumed during the production of the carbon dioxide bubbles and therefore does not contribute to the purification effect.

Example 6: Removal of limescale deposits by acidic formulations

A comparison of the limescale removal effectiveness of formula E1, water and the four different cleaning formulations of Table 3 was made.

The following procedure was performed to determine the effectiveness of limescale removal.

1.9 cm (0.75 inch) x 1.9 cm (0.75 inch) x 0.95 cm (0.375 inch) marble cubes were rinsed thoroughly with deionized water and dried in an oven at 105°C for one hour . For each product sample, 4 marble cubes are tested.

5 cm (2 inch) aluminum pans are labeled and weighed with an analytical balance. The label and weights are recorded as deadweight. A cube of marble is placed in the crucible, polished side up, then weighed again and the weight recorded. The initial weight is the weight of the marble cube in the crucible minus the weight of the crucible (dead weight).

Approximately 40 grams of the test product is placed in a jar or suitable container. The size of the jar or container must be large enough to allow the marble to be completely submerged in the test product. The marble cube is completely immersed, polished side up, in the test product using tweezers. The marble cube is soaked in the test product for one minute. The marble cube is removed from the test product and immediately immersed in a beaker of deionized water. The marble cube is then placed on a perforated spoon and rinsed with deionized water for 30 seconds. The marble cube is placed back in its aluminum crucible and dried at 105°C for one hour. The marble cubes are then allowed to cool in a desiccator and weighed again. The final weight is the weight of the marble cube in the crucible after testing and drying, minus the weight of the crucible (dead weight).

The percentage of dissolved limescale is measured as [(initial weight - final weight)/initial weight] x 100.

The average of the four test results is given in Table 6. Table 6: E1 C4 C5 C6 C7 water Limescale removal 87.91 54.3 84.90 83.32 51.76 33.33

It can be seen that formula E1 provides better limescale removal than any of the comparative examples.

Although Formula E1 differs from Formula E6 in foam generation, the cleaning structure is similar and similar results are expected from Formula E6 in removing limescale. More specifically, all of the sodium carbonate or sodium bicarbonate is consumed during the production of the carbon dioxide bubbles and therefore does not contribute to the purification effect.

Example 7: Tablet stability of the acidic formulations

Accelerated storage stability and corrosion studies were performed on Formulation E6 tablets. The studies were conducted by an independent laboratory in accordance with US Environmental Protection Agency Good Laboratory Practice (GLP) regulations encoded under 40 CFR Part 160. The tablets tested contained (3) different fragrance variants identified as E6-1, E6-2 and E6-3 in Table 7 below. Three (3) tablets of the same fragrance were contained in one (1) flow pack. The tablets in the flow-wrap packaging were stored at 54 ± 2°C for fourteen (14) days. Corrosion characteristics (referred to as “Corrosion” in Table 7 below) were determined by two separate individuals and included a visual inspection of the container for signs of corrosion. The physical assessment (labeled "Physical" in Table 7 below) was performed by two different people and involved visual inspection of a portion of the tablet in a small weighing boat. Analysis for any phase separation and/or clumping was part of the physical assessment. The laboratory performed a full method validation of the assay used to determine the citric acid concentration. The analytical result was calculated from the average of the analyzes for each of the three (3) tablets contained in the flow-wrap package. Table 7: test and time E6-1 E6-2 E6-3 Day 0 weight 25.88g 25.86g 25.85g Day 14 weight 25.20g 25.19g 25.27g Day 0 corrosion None None None Day 14 corrosion None None None Day 0 Physical Dry cylindrical solid without phase separation or clumping Dry cylindrical solid without phase separation or clumping Dry cylindrical solid without phase separation or clumping Day 14 Physical Dry cylindrical solid without phase separation or clumping Dry cylindrical solid without phase separation or clumping Dry cylindrical solid without phase separation or clumping Day 0 analysis 55.02% citric acid 54.32% citric acid 55.11% citric acid Day 14 analysis 54.34% citric acid 55.50% citric acid 54.39% citric acid

The results in Table 7 show that Formulation E6 tablets are stable for two (2) years at ambient conditions. Table 7 further shows that the flow wrap packages and the tablet formulations successfully prevent weight gain due to water absorption from the air (hygroscopicity).

Example 8: Packaging stability of the acidic formulations

Accelerated storage stability and corrosion studies were performed on Formulation E6 tablets. Three (3) tablets were contained in one (1) flow pack. Two different tubular bag materials were tested. Tubular bag A in Table 8 below is a three-layer tubular bag with an 8 micron aluminum layer sandwiched between a 30 micron polyethylene layer and a 12 micron PET layer. The tablets were placed next to the PE layer. Flowpack B in Table 8 below is a 30 micron aluminum metallized oriented polypropylene film. The tablets were placed next to the PP layer. Both flow packs A and B are commercially available in sheets that can be used to form the flow pack. The flow-wrap containers were formed by three seams in overlapping sections of the laminate material, a top seam spanning a width at one end, a bottom seam spanning the width at the opposite end, and a side seam spanning a length between the top and the bottom seam, thereby forming a tubular package having a length of from about 110 mm to about 130 mm (ie, side seam dimension) and a width of about 20 mm to about 30 mm (ie, top or bottom seam dimension). The tablets in the flow-wrap packaging were stored at 40°C and 75% relative humidity for eleven (11) weeks. As can be seen in Table 8 below, flow-wrap package B showed a significant weight gain, indicating moisture penetration and absorption by the tablets. As time progressed, the tablets in tubular bag B changed in appearance due to moisture absorption, changing color and surface texture from glossy to matte. In tubular bag A, there were no visual changes to the tablets. Table 8: Tubular bag A Tubular bag B Day 0 weight 19.4g 19.23g week 1 weight 19.4g 19.23g week 2 weight 19.32g 19.33g week 3 weight 20.04g 20.01g week 4 weight 19.4g 21.10g week 5 weight 19.5g 19.04g week 6 weight 19.6g 21.42g week 7 weight 19.7g 19.53g week 8 weight 19.8g 32.14g week 9 weight 19.44g 42.1g week 10 weight 19.55g 53.10g week 11 weight 19.2g 52.54g

Accelerated storage stability and corrosion studies were performed on solutions prepared from tablets of formulation E6. The tablets tested contained the same fragrance as E6-2 in Table 7. The studies were performed by an independent laboratory in accordance with the US Environmental Protection Agency's Good Laboratory Practice (GLP) code code under 40 CFR Part 160. Test solutions were prepared by dissolving three (3) tablets in 750 mL of hard water (400 ppm AOAC) in polyethylene terephthalate (PET) bottles. Nine (9) PET bottles containing the test solutions were stored at 54 ± 2°C for fourteen (14) days. Corrosion characteristics (referred to as “Corrosion” in Table 9 below) were determined by two different individuals and included a visual inspection of the container for signs of corrosion. This analysis included a visual inspection of lids, liners, seams and container sides. The physical assessment (referred to as “Physical” in Table 9 below) was performed by two different individuals and included visual inspection of the solution in a 50 mL beaker. Analysis for any phase separation and/or clumping is part of the physical assessment. The laboratory performed a full method validation of the assay used to determine the citric acid concentration. The analysis was performed in triplicate for each bottle. The results in Table 9 are the mean of three (3) different bottles, with the mean of bottles 2 (1.48), 3 (1.46) and 4 (1.46) for the Day 0 analysis and the mean of bottles 5 (1.6), 6 (1.49) and 7 (1.44) were used for analysis on day 14.

Example 10: Microbiological tests of the acidic formulations

Microbiological potency test studies against bacteria and viruses were performed using solutions prepared from tablets of formulation E6. The studies were performed by an independent laboratory in accordance with the code of practice under 40 CFR Part 160 US Environmental Protection Agency Good Laboratory Practice (GLP). Test solutions were prepared by dissolving three (3) tablets in 750 mL of hard water (400 ppm AOAC) in polyethylene terephthalate (PET) bottles with a spray head. The bottles were shaken to ensure homogeneity and puffs were dispensed to prepare the spray head prior to testing. Three (3) pump sprays delivered an average of 2.0ml.

Viral Testing (ASTM International E1053-20): The solution was sprayed from a distance of six to eight inches onto the virus carriers in a horizontal position (three pump sprays). A control slide was not treated with the solutions. The carriers were held at the indicated conditions and for the contact time indicated in Table 10 below. Shortly before the end of the exposure period, the carriers were scraped off with a cell scraper to resuspend the contents. The contents were passed through a Sephadex column using the syringe plunger to detoxify the mixtures. The filtrates were then serially scaled in a 10-fold dilution and analyzed for infectivity and/or cytotoxicity.

Bacterial Testing (AOAC Germicidal Spray Method 961.02): The bacterial culture was spread evenly over individual glass slides contained in a Petri dish. The slides were allowed to dry for 30 minutes. The test solution was sprayed onto the slides from a distance of six to eight inches (three pump sprays). A control slide was not sprayed with the solution to confirm growth. After the five (5) minute contact time, the excess liquid was drained from the slide without the slide touching the Petri dish or the filter paper. All subcultures were intubated for 48 hours at 35-37°C. After intubation, the subcultures were visually inspected for the presence or absence of visible growth.

The results in Table 10 show that the disclosed tablets form solutions that provide biocidal protection against bacteria and viruses, including hard-to-kill bacteria such as S. aureus and viruses such as rhinovirus. No average professional would expect this activity based on the concentration of citric acid in the solution.

Example 11: pH, dissolution and foam height of basic formulations

The carbonate or bicarbonate listed in Table 11 below was placed in a rotary mixer and mixing was started. Exemplary rotary mixers include the Vidax™ or VH-14 mixers. Those of ordinary skill in the art will recognize that the mixing conditions are batch size dependent. For a batch size of 600 kg in a stainless steel container, an exemplary suitable mixing speed may range from about 6 revolutions per minute (rpm) to 12 rpm, preferably from 8 rpm to 10 rpm. The liquid EO4 or EO6 was sprayed onto the carbonate or bicarbonate while mixing. Mixing was continued until the mixture was visually uniform. After visual uniformity was achieved, CA was added to the mixture. Mixing is continued until the mixture is visually uniform. F, MGDA, D and BKC were added sequentially to the mixture with continued mixing. Mixing was stopped when the batch was visually uniform. The powder density and flowability of the resulting mixture were analyzed. Applicants believe that active core assays will show that the individual components are evenly distributed. This analysis may or may not be performed on each individual batch. The resulting mixture has a density of about 0.8 g/cm ³ . The resulting powder was divided into portions each having the desired tablet weight. Each individual serving was placed in a tablet form. The tablet was hand compressed using a tablet press.

750 mL (25.4 ounces) of tap water was heated to 50°C and placed in an 800 mL PET bottle. Two more 800 ml PET bottles were prepared in the same way. For each formulation, three (3) tablets averaging 10g each were added to the tap water in the bottle. No mixing was required due to the effervescent nature of the tablets. The dissolution time was measured. Any foam overflow was also noted. 3 Figure 12 is an example image of a positive foam overflow result. Due to the effervescence, the formulation is initially cloudy but becomes clear after about an hour. The formulations and test results are given in Table 11: Table 11: raw material C8 E8 E9 BKC 11 (4.4) 11 (4.4) 11 (4.4) APPROX 12 12 12 bicarbonate 50.37 0 0 carbonate 0 50.37 50.37 EO4 0 0 7.5 EO6 7.5 7.5 0 GLDA 8.1 (6.5) 8.1 (6.5) 8.1 (6.5) f 11 11 11 D 0.03 0.03 0.03 Resolution time (in minutes) ~7 ~14-15 ~14-15 foam overflow? Yes no no pH ~7.5 ~10 ~10

As can be seen from Table 11, the inclusion of sodium bicarbonate resulted in foam overflowing from the top of the bottle's spray head. Foam overflow creates a negative consumer experience because the cap or spray head cannot be placed on the bottle immediately without causing mess. In addition, water and detergent can be lost, which negatively affects the effectiveness of the cleaner.

Example 12: Removing baked-on (polymerized) fats with basic formulations

Soil Removal Test:

The blends in Table 11 were tested for their effectiveness in removing baked-on deposits representative of those typically found on stove tops and oven surfaces from hard surfaces. The following materials and protocols were used. The cleaning results are given in the following tables.

Preparation of the standardized pollution:

Part 1:

1 kg soil mixture was prepared and used in the following tests. The stain is designed to replicate real baked-on cooking residue. A premix was formed containing, by weight, about 40-45% oil; about 10-17% pie filling; about 25-35% fatty ground beef; about 1-3% spices with the balance being deionized water. The premix ingredients were combined on a baking sheet and baked at 400°F (205°C) for 2 hours. After baking, the liquid was drained and, while still hot, filtered through several layers of cheesecloth. The resulting filtrate must be clear and free from particles. The filtrate can be refiltered to achieve clarity. Once prepared, Part 1 of the greasy soil can be divided into smaller batches and kept refrigerated in jars for up to 1 year.

Part 2: 100% cocoa, unsweetened chocolate bar. Finished pollution: 85-95% pollution part 1; 5-15% pollution Part 2.

Set the water bath to 45°C (113°F). Put the soiled glass part 1 in the water bath to melt it. Once melted, pour the desired amount of contaminant into a smaller beaker and add to a batch of water. Reduce the temperature of the water bath to 38°C (100°F). Add desired amount of chocolate. Melt chocolate in contamination part 1 and mix/stir with mixing stick. Leave the beaker in the water bath while stirring to maintain temperature and homogeneity.

Preparation and soiling of tiles:

Preheat oven to 165°C (329°F). A number of rectangular, white, porcelain-enamelled steel tiles of the same size were cleaned with a mild detergent. The tiles were then rinsed with ethanol and allowed to air dry. Prior to application of the soil, the surface reflectance "RI" for each cleaned tile was assessed using a digital imaging device (such as an Ortery™ Photosimile 200 PhotoBooth or similar). The R1 value for each tile was recorded.

cleaning test:

The finished soil prepared above is preheated to 38°C (100°F) using a water bath. A 1.7 g aliquot of the heated soil was applied to one surface of the tile and spread evenly thereon with the tile lying on a horizontal laboratory bench, resulting in a final soil weight of between 1.0 and 1.10 g on each tile led. The tiles were placed on trays and baked in a convection oven at 329°F (165°C) for 90 minutes to form the baked on greasy soil. The tiles were then allowed to cool to room temperature (about 20°C-22°C, about 68°F-72°F) for 24 hours. The test tiles were then used to evaluate the cleaning performance of a composition. Before applying a cleaning composition to a tile to evaluate cleaning performance, the surface reflectance "R2" for each soiled tile was evaluated using a digital imaging device. The R2 value for each tile was recorded.

The effectiveness of a composition in removing soil at room temperature was evaluated using a Gardner Abrasion Tester. Individual cellulose sponges were washed in a washing machine and subjected to three rinse cycles. Prior to testing, the sponges were wetted with water and hand squeezed to remove excess water.

A measured amount of between 15 and 25 grams of a test mixture was applied to one surface of the damp sponge. Immediately thereafter, the tile was placed in a Gardner Abrasion Tester which performed a specified number of cleaning cycles (each cycle consisting of a forward and a reverse stroke). After the cleaning cycle was complete, the tile was removed from the tester and the portion of the tile abraded by the sponge was gently rinsed with cold tap water for up to 5 seconds. The tested tile was then allowed to dry. The surface reflectance "R3" of the part of the tile rubbed by the sponge was evaluated with the digital imaging device. The R3 value for each tile was recorded. Each mixture was tested on four (4) tiles resulting in four (4) replicates for each mixture tested.

The percentage of baked-on greasy test soil removed from each tile was determined using the following equation: $$\%\text{pollution removal}=\left[\left(\text{<figure-callout id="1" label="R" filenames="DE202022104360U1\_0002.png,DE202022104360U1\_0005.png" state="{{state}}">R</figure-callout>}1-\text{R}2\right)/\left(\text{<figure-callout id="3" label="R" filenames="DE202022104360U1\_0005.png,DE202022104360U1\_0008.png" state="{{state}}">R</figure-callout>}3-\text{R}2\right)\right]\times 100$$

The test results and the identity of the mixtures tested are presented in the following tables. Also indicated is the percentage of soiling removed. The results reported are the numerical averages of the percent soil removed for the four (4) tiles used in the test. Table 12: formulation C8 E8 water cleaning cycles 18 18 18 % pollution removal 5.26% 78.51% 8.02%

Based on the results in Table 12, Formulation C8 containing sodium bicarbonate performed inferior to both Formulation E8 and water. Formulations C8 and E8 have the same base formula, with C8 containing sodium bicarbonate and E8 containing sodium carbonate. It is believed that the drop in pH of formulation C8 compared to E8 causes the inferior soil removal of caked fat. Table 13: formulation E8 E9 water cleaning cycles 11 11 11 % pollution removal 31.13% 5.93% 7.34%

As can be seen from Table 13, formulation E9 containing a 4 EO surfactant was compared to formulation E8 containing 6 EO surfactant. Formulations E8 and E9 share the same base formula except for differences in the EO alcohol ethoxylates used (4 EO vs. 6 EO). Formulation E9 performed inferiorly to both Formulation E8 and water in its ability to remove caked fat effectively.

Example 13: Carbonate vs. Bicarbonate Test

Samples were prepared in a glass jar by adding 5 g of citric acid DC sold by JBL and 5 g of either sodium carbonate or sodium bicarbonate sold by Novacarb or Solvay. The initial weights of each jar were measured. The jars were then capped with punctured parafilm and placed in the 40°C/75% relative humidity chamber. Each day the vessels were removed from the chambers and their weights recorded. 7 . Figure 12 shows a plot of vessel weight versus time. The results of this study show that the carbonate-citric acid mixture gained weight while the bicarbonate-citric acid mixture lost more than 1 g in weight. These results suggest that the moisture content threshold required to start the autocatalytic reaction of the citric acid with the bicarbonate is much lower than that of the carbonate-citric acid mixture. These results suggest that using a carbonate anion in effervescent formulations offers stability advantages over using a bicarbonate anion by allowing more moisture to be absorbed in the final product before the autocatalytic reaction begins. Obviously, formulations containing less than 10% by weight carbonate, or containing more citric acid than bicarbonate, may not exhibit a similar phenomenon.

Example 14 Bactericidal Efficacy of Basic Formulations

Formulation E8 was tested to determine minimal bactericidal activity under dirty conditions against Staphylococcus aureus (ATCC 6538), Pseudomonas aeruginosa (ATCC 15442), Escherichia coli (ATCC 10536), Enterococcus hirae (ATCC 10541).

Three (3) ten (10) gram tablets of Formulation E8 were added to 750 ml of hard water (plain). 50% and 1% dilutions were made from the pure solution.

8 ml aliquots of the formulation have been tested according to EN 1276:2019 (Chemical disinfectants and antiseptics - Quantitative suspension test for the determination of the bactericidal activity of chemical disinfectants and antiseptics in the food, industrial, household and institutional sectors) of the European Committee for Standardization. The log ₁₀ reduction results are summarized in Table 14. Table 14: sample S. aureus P. aeru. E. coli E. hirae 5 minutes exposure 20°C ± 1°C 5 minutes exposure 20°C ± 1°C 5 minutes exposure 20°C ± 1°C 5 minutes exposure 20°C ± 1°C Pure > _5.17log10 > _5.24log10 > _5.09log10 > _5.09log10 50% > _5.17log10 > _5.24log10 > _5.09log10 > _5.09log10 1% _4.18log10 < _{1.87log10 3.17log10} >5.06

It can be seen that the formulation has bactericidal activity in suspension both neat and at 50% dilution. One of ordinary skill in the art will recognize that germ kill is not affected by the degree of ethoxylation of the alcohol ethoxylate and would expect similar results from Formulation E9.

0.1 ml aliquots of the formulation were prepared according to EN 13697:2015 + A1:2019 (Chemical disinfectants and antiseptics - Quantitative surface test to determine the bactericidal and/or fungicidal effect of chemical disinfectants on non-porous surfaces in the food, industrial , household and public institutions) tested against P. aeruginosa by the European Committee for Standardization. The log ₁₀ reduction results are summarized in Table 16. Table 16: sample P. aeruginosa 10 mins exposure 18-25ºC Pure _4.14log10 50% _3.79log10 1% < _1.46log10

It can be seen that the neat formulation has surface bactericidal activity. One of ordinary skill in the art will recognize that germ kill is not affected by the degree of ethoxylation of the alcohol ethoxylate and would expect similar results from Formulation E9.

Example 15 Levurocidal Efficacy of the Basic Formulations

Formulation E8 was tested to determine minimal yeasticidal activity under soiled conditions against Candida albicans (ATCC 10231).

Three (3) ten (10) gram tablets of Formulation E8 were added to 750 ml of hard water (plain). 50% and 1% dilutions were made from the pure solution.

8 ml aliquots of the formulations were tested against EN 1650:2019 (Chemical disinfectants and antiseptics - Quantitative suspension test for the determination of the fungicidal or yeasticidal activity of chemical disinfectants and antiseptics in the food, industrial, household and public establishment sectors) of the European Committee for Standardization C. albicans tested.

0.1 ml aliquots of the formulations were prepared according to EN 13697:2015 + A1:2019 (Chemical disinfectants and antiseptics - Quantitative surface test to determine the bactericidal and/or fungicidal effect of chemical disinfectants on non-porous surfaces in the food, industrial , household and public facilities) tested against C. albicans (on surface) by the European Committee for Standardization.

The suspension and surface area log ₁₀ reduction results are summarized in Table 17. Table 17: sample suspension surface 15 minutes 15 minutes exposure exposure 20ºC ± 1ºC 18-25ºC Pure > _4.03log10 >4.91 50% _3.85log10 >2.86 1% _1.25log10 1.98

It can be seen that the neat formulation has levurocidal activity under both suspension and surface test conditions. One of ordinary skill in the art will recognize that germ kill is not affected by the degree of ethoxylation of the alcohol ethoxylate and would expect similar results from Formulation E9.

Example 16 Virucidal Efficacy of the Basic Formulations

Formulation E8 was tested to determine minimal virucidal activity against influenza virus type A (2009-H1N1) (Novel H1N1), respiratory syncytial virus (RSV), SARS coronavirus 2 (SARS) and vaccinia virus.

Three (3) ten (10) gram tablets of Formulation E8 were added to 750 ml of hard water (plain). 50% and 1% dilutions were made from the solution. 1.6 ml aliquots of the formulations were tested based on BS EN 14476:2013 +A2:2019 (Chemical disinfectants and antiseptics - Quantitative suspension test to determine the virucidal effect in human medicine) of the European Committee for Standardization against Novel H1N1 (CDC 2009712192 ), RSV (ATCC VR-26, Strain: Long), SARS (BEI Resource NR-52281, Strain: Isolate USA-WA1/2020), and Vaccinia (ATCC VR-119, Strain: WR). The log ₁₀ reduction results are summarized in Table 18. Table 18: sample Novel H1N1 RSV SARS Vaccinia 10 mins 10 mins 10 mins 5 minutes exposure exposure exposure exposure 20ºC ± 1ºC 20ºC ± 1ºC 20ºC ± 1ºC 20ºC ± 1ºC clean dirty dirty dirty conditions conditions conditions conditions Pure > _4.5log10 > _4.0log10 > _4.33log10 > _4.67log10 50% _≥5.5log10 > _4.0log10 > _{5.33log10 ≥4.67log10} 1% _{0.67log10 0.17log10 0.33log10} 0

It can be seen that the formulation has virucidal activity in suspension both neat and at 50% dilution. One of ordinary skill in the art will recognize that germ kill is not affected by the degree of ethoxylation of the alcohol ethoxylate and would expect similar results from Formulation E9.

Additional virucidal testing of formulation E8 was performed under clean conditions at room temperature (18-25°C) against vaccinia virus. Neat, 50% and 1% solutions were tested at contact times of ten (10), fifteen (15) and twenty (20) minutes. 100 µl aliquots of the formulations were tested against the vaccinia virus, Ankara strain (MVA, ATCC VR-1508) (Host cell line BHK-21, ATCC CCL-10). The log ₁₀ reduction results are summarized in Table 19. Table 19: sample 10 mins 15 minutes 20 minutes Pure _{3.0log10 3.0log10 3.0log10} 50% _{4.0log10 4.0log10 4.0log10} 1% _{0.66log10 0.66log10 0.66log10}

It can be seen that the formulation has surface virucidal activity both neat and at 50% dilution. One of ordinary skill in the art will recognize that germ kill is not affected by the degree of ethoxylation of the alcohol ethoxylate and would expect similar results from Formulation E9.

Example 17: Packaging stability of the basic formulations

Additional accelerated storage stability and corrosion studies were performed on tablets of formula E8. Three (3) tablets were contained in one (1) flow pack. Two different tubular bag materials were tested. Tubular bag A in Tables 20a-e below is a three-layer tubular bag with an 8 micron aluminum layer sandwiched between a 30 micron polyethylene layer and a 12 micron PET layer. The tablets were placed next to the PE layer. Flowpack B in Tables 20f-j below is a 30 micron aluminum metallized oriented polypropylene film. The tablets were placed next to the PP layer. The flow-wrap containers were formed by three seams in overlapping sections of the laminate material, a left end seam spanning a width at one end, a right end seam spanning the width at the opposite end, and a side seam spanning a length between the end seams. thereby forming a tubular pack having a length of from about 110 mm to about 130 mm and a width of from about 20 mm to about 30 mm. The tablets in the flowpack were stored under the conditions given in the tables below. As can be seen from Tables 20a-j below, the dissolution time for tablets stored in tubular bag B is significantly higher than the dissolution time for tablets stored in tubular bag A at higher temperature and humidity conditions, providing a better barrier to atmospheric moisture indicates. Applicants believe that the liquid alcohol ethoxylate may have penetrated the polypropylene layer and slightly eroded the aluminum.

Example 18: Alternative basic formulations

Additional testing was conducted for an alternative base formulation given in Table 21 below. As shown in Example 12 and Table 13 above, Formulation E9 showed poorer polymerized greasy soil removal than Formulation E8. The shorter chain length ethoxylates are not able to dissolve the fat but can penetrate the polymerized layer very well. A combination of a longer chain ethoxylate and a shorter chain ethoxylate allows the formulation to penetrate the polymerized layer and erode the soil.
